Finding the maximum area, or largest triangle, in a semicircle is very simple. At first you might think that there is not enough information, but remember that they want the maximum area. The triangle is the largest when the perpendicular height shown in grey is the same size as r. This is when the triangle will have the maximum area. The formula ½× b × h is the area of a triangle, and in

Finding the arc length of semicircle? Yahoo Answers

Can we find the length of a semicircle, given its radius? Spoiler alert: yes. It ought to be half the circumference of a circle with the same radius, don't you think? And let's say we wanted to find the length of a quarter-circle with a given radius. Shouldn't it be one-fourth of the circumference of a circle with the same radius?

How to Determine the Dimensions for the Least Expensive

The unit length is a reference length. Thus, if we decided to make one segment be a reference, then we can say the length of the segment is 1. Therefore, if the semicircle is given then the radius should be a unit length here. By copying the semicircle, we can easily figure out the ratio . Since the semicircle given, we fix =1, then . First, we have to construct , and then by using the
